通达信VOL主力买卖指标（资金型）指标公式
买卖信号
- **持币信号**：当SAR(10,2,20) >= H（最高价）时，显示绿色圆点（CIRCLEDOT），表示应持币观望 - **持股信号**：当SAR(10,2,20) <= L（最低价）时，显示蓝色圆点（CIRCLEDOT），表示应持股待涨
用法
这是一个综合性的资金流向分析指标，主要适用于以下场景： 1. **资金监测**：通过"主动买"和"主动卖"区分主动买入和主动卖出资金，差额为净主动买入 2. **大单分析**：将资金分为超大单、大单、中单、小单，分别计算净流入，用于判断不同规模资金的动向 3. **持仓参考**：利用SAR(10,2,20)指标判断持币/持股状态，当价格上穿SAR时持股，下穿时持币 4. **看盘辅助**：通过DRAWRECTREL绘制资金流向柱状图，直观显示各类资金的净流入情况 注意事项： - 该指标需要Level-2行情数据支持（L2_AMO函数） - 仅在日线周期以上级别有效（PERIOD=5表示日线） - 预测量仅在当日开盘前有效（使用FROMOPEN计算） - 资金流向仅供参考，需结合其他分析方法综合判断
